The Cosmological Term
From the Lagrangian section
Where 
is the total density of matter+radiation+vacuum. By definition
For a spherical distribution of mass,
The cosmological term is (see page for calculation of N the dimensions of Space Time.
Substituting 
For 
the cosmological term is
Hubbles constant is 
, the cosmological term evaluates to
The parameter
which agrees well with observations.
The Dark Energy makes up 70% of the Universe and is made up of particles of energy
